The invention relates to door locks.

The primary object of the invention `is to provide an improved doorylock which may be set *so as to be operable by the handles on both sidesofthe door or operable by one handle only, and either operable orinoperable, by a key from the outside of the door.

Other objects of the invention will be apparent from a considerationA ofthe following detailed description.

f The invention consists in theY several novel :features hereinafter setforth and more particularly defined by claims at the conclusion hereof.f p

In the drawings: Fig. 1 is an .elevation of the locking bolt in its caseand its Vshifter device, one section of the case being removed forillustrative purposes and the bolt being shown in its operative orextended position.

Fig. 2 is a similar view showing the bolt retracted. Fig. 3 `is asection taken on the line y3 3 of Fig. 1, the slidable stem foractuating the bolt being shown in the position assumed when the boltisoperable by either of the handles. Fig. ll is a View similar to Fig. 3showingthe stemin the posi- "tion assumed when it has been shifted tolock the ybolt against operation by its rotation. Fig. 5 isa Vfrontviewr of the outer f rhandle showing the key slot in the same.

Fig. 6 is a section taken on the line 6-.6 of Fig. 1, showing lthevarious parts in position to render the bolt operable by either of thehandles. Fig. 7 is a viewsimilar to Fig. y6, showing the stem locked sothe bolt will be inoperable by the outside handle or by the' ykey-'controlled device. Fig. 8 is a perspective of the rotary vdevicefor shifting the wbolt. Fig. 9 is aperspective of the slidable stem andthe kkey-operated element for shift ing the stem.y Fig. 10 isaperspective of they key. Fig. 11` isf a perspective of the outerhandle. l

The inventionk is exemplifiedV in a lock comprising a case ycomposed ofa main seotion or bodyllil and a removable section 15. Thiscase isinserted in a door 16. A locking' bolt 17 is longitudinally slidable inthe case'and itsv outer end is adapted to pass into the usual socket inthe door frame to hold the door ,i closed. The inner portion ofthe boltis divided to 4form upper and 'lower members 18 to straddle a rotatableshifter member 19. 'At its inner end the bolt isprovided with anabutment adapted to retract the boltwhen said member is rotated 1neither direction from its normal position shown in Fig. 1. Shiftermember 19'has i integrally formed therewith a hub 22 journal'led in anopening in case-section 15 and Aa hub 23 journalled in case-section 14.

be engaged by arms 21 or member 19 to hole, and is adapted to rotatesaid member.

A spring 26 engages the bolt 17, and its inner end is coiled around ashifter stem 27 which has at its inner'end a terminal 28 to engage thestem 25.2 Spring 26 acts to hold normally the bolt' 17 in its extendedor locked position. The abutting faces between stem 25'and terminal 28are shaped to cause the spring to hold the stem in its normal position,and to retract the stem after it has been rotated ineither direction.Stem 25 is provided with .two notches 25a and 25 intov which .theterminal 28 is pressedby the spring, so as to hold the stem in twolongitudinal positions. Lugs 30 are formed on the stemr25, and areadapted, when the stem is in the position shown in Figs. 4 and 7 toente'r'notches 31 in the hub 23 of shifting member 19 and notches 32 inthe members k18 oftheI locking bolt to secure thebolt and the shiftingmember against Vrelative-,movement, so that said member will be lockedagainst .rotation and will be inoperative to withdraw the bolt. When thelugs `30 are. in thel positionillustrated inFigs. 3 and and in the otherof which the bolt will be operable by the rotation of said member ineither direction.

At the inner side of the door a bearingplate 34 is secured. A v hub 35on aninside handle isy rotatably and slidably heldin said plate (seeFig. 6). A screw 37 in the hub secures the handle 86 to the stem 25 sothatithe latter Will be `rotatable by the han- 10 dle, andlongitudinally movable between its alternative positions by the handle.When the handle 36 is in the position shownfin Fig. 6, the bolt 17 maybe Withdrawn against the force ofthe spring by rotation of the .handleand loperation of st em 25, lugs `30,

l i i ufb23, arms 21, and abutment 20. A bearingp'lateB'S isr secured tothe outer side .of the door. vA hub 39-011 an outside handle 40 ,isrotatablyniounted in said plate. 'A 20 shoulder 41 ,on hub 39A engagesthe outer .faceof an annular rib 42 in bearing-pl`ate 38, and lugs 43 onthe hub 39` engage the finner lfa ce' jc f rib V42 toV interlock plate38 and handle`40 to secure said handleagainst longitudinal movement.lRib 42 is formed ,v

.vvith notches through which lugs 43 may be inserted ,in assembling .thehandle 40 and VrpflateBS, the ,lugs 4 3 having an operative frange in`which theyyvill `be kept out of A alignment With `said slots afterassembling. "When the stem 25` is Vvin the position"illus- .tratedinfFigs an'd6, the stem is rotatable by the o uterh'andle 4 0, as -Wellas bythe inner handle 36,jand consequently the bolt 17may be retracted,either from the inside oroutsidelof the door. Vhenthe stem 22 5 is inthe position illustrated in Figs. 4 and ,the boltl-T will be inoperableby the Qut-V side handle 40. I 40 v.A key ioperable .device yis providedV for .st iftingI` the 4stem 25 longitudinally 'When it is desiredthatthe door may be,unlocked from the outside by a suitable key. VThisvdevice vo )n sists .of a l`member44 which is 45 1 S li dably connednina socket 45 in handle 40. and is provided at its innerend With` ahQokQor tooth 46. The latter engages a hook or tooth 47 on the vouterend of stem Av2 3, so .tl 1at the stem `may be shiftedilongi- 50 ytudinally by key-operable member v44. Member 44is provided With a lug 48fconj fined in arecess 49 inhandle 4 0, to hold themember againstrotation in the handle. The upper portion of member 44 is convex, randhas'.longitudinally.extending shoulders l50at the sides thereof. rAtooth 51 isformedf A )'n one ofthe shoulders 50. VThe outer end ofsocket 4 5 is permanently Closed by va lug 52 which isfformed Withakey-slot 53 W lich rcuate in cross seetion to admit a semif hlicalkeyv54 l(see-Figs. Y5 and 10).

At times Vit is'desirable to lock ,the b olt 17 sojthat ,it cannot beoperated .from the outside with ake vand for lthat purpose a vdevice isprovif ed for lookinguthe vste'n1`25 in the position in which it locksthe bolt 17 against retraction, andthis/consists of a ring which isrotatablearound the `hub @5pt the inside handle-36.
